摘要：
Vessel integrated power system (IPS) based on medium voltage direct current has broad application prospect. With the improvement of power rating and voltage rating of IPS, as more and more energy storage units are applied in IPS, the traditional unidirectional two-port converter fails to meet new application requirements. Therefore, a modular three-port DC-DC converter for Vessel IPS is proposed. Medium voltage DC grid, low voltage DC grid and distributed energy storage unit are connected together in this three-port converter. Bidirectional power flow is achieved in each port. Topology and operation principle of this three-port converter are analyzed. The power flow modes at different operation states are then analyzed. Adaptive control scheme for the converter is built based on the power flow modes analysis. The principle analysis and control scheme are verified through a modular three-port converter prototype with a rated power of 20kW. © 2020, Electrical Technology Press Co. Ltd. All right reserved.
